Izi-separator ezijikajikayo yizisetshenziswa zokucubungula amaminerali ezisekelwe emandleni adonsela phansi, eziklanyelwe ukuhlukanisa izinhlayiya ngokusekelwe ku-density (ubukhulu) nosayizi wazo. Isakhiwo sazo esilula kodwa esisebenzayo sivumela ukuhlukaniswa okuqhubekayo kwezinsimbi ezinhle kakhulu, okwenza zibe yigugu ekuthuthukiseni amaminerali afana ne-hematite, igolide, nezinye izinsimbi ezingezona ezensimbi. Ngokungafani nezinye izindlela zokuhlukanisa ezisebenzisa amandla amaningi, izi-concentrator ezijikajikayo zisebenzisa amandla emvelo adonsela phansi kanye ne-fluid dynamics ukuze zithole amazinga aphezulu okubuyisa. Le ndlela ayinciphisi nje kuphela izindleko zokusebenza kodwa futhi inciphisa nomthelela ombi emvelweni ohlobene nokucubungula amaminerali.

Isihlukanisi esijikajikayo siqukethe umgudu ojikelezayo lapho uketshezi lugeleza phansi, okuvumela izinhlayiya zamaminerali ezisindayo ukuba zihlale eduze komphetho wangaphakathi ngenkathi izinhlayiya ezilula zihamba ziya emaphethelweni angaphandle. Le ndlela yokuhlukanisa ikwazi kakhulu ukuphatha izinhlayiya ezinhle ezivame ukuba nzima ukuzicubungula kusetshenziswa imishini evamile. Ubuchwepheshe, ukusebenza kahle, nokuvumelana kwezihlukanisi ezijikajikayo kubenza babe yisisekelo sobuchwepheshe ezitshalweni zokuhlanza amaminerali emhlabeni wonke.

Izimboni zesimanje zokucubungula izimbiwa zibhekene nengcindezi eyandayo yokwamukela izindlela ezizinzile ngenxa yemithetho yezemvelo kanye nokwanda kokwazi ngemvelo phakathi kwabathintekayo. Izindlela zendabuko zokuhlukanisa izimbiwa zihlanganisa amakhemikhali nezinqubo ezisebenzisa amandla amaningi ezingadala izingozi ezindaweni eziphilayo nasezempilweni yabantu. Kulo mongo, izixazululo ezinganakile zemvelo njengokuhlukanisa nge-spiral zinikeza izinzuzo ezibalulekile ngokunciphisa ukusetshenziswa kwamakhemikhali nokusetshenziswa kwamandla.

Ngokusebenzisa izimiso zokuhlukanisa ngamandla omzimba (gravity separation), izihlukanisi ezijikajikayo zinciphisa ukuncika kumakhemikhali okuhlanganisa (flotation reagents) noma izinsimbi ezisindayo, ezingangcolisa imithombo yamanzi nomhlabathi. Izidingo zamandla aphansi ezihlukanisi ezijikajikayo nazo ziguqulela ekunciphisweni kokukhishwa kwe-greenhouse gas, okuhambisana nemigomo yomhlaba wonke yokunciphisa ukungcola komoya. Ukugcizelela ubuchwepheshe obuhambisana nemvelo akusizi nje izinkampani ukuthi zithobele imithetho kodwa futhi kuthuthukisa izithombe zazo zenhlalakahle yezinkampani, kukhuthaza ukwethenjwa yimiphakathi namakhasimende ngokufanayo.

Ukuqonda umgomo wokusebenza wezihlukanisi zomsungulo kubalulekile ekuthuthukiseni ukusebenza kwazo. Inqubo iqala ngokudlulisa inhlanganisela yomhlaba oqotshwe kahle namanzi phezulu komgodi womsungulo. Njengoba inhlanganisela igeleza phansi, amandla e-centrifugal kanye nokuwa kwesihlabathi kuthinta izinhlayiya, kubangele ukuhlukaniswa ngokusekelwe ekuphambaneni kwe-density. Amaminerali asindayo, anesisindo esiphakeme kakhulu, ahamba aye engxenyeni engaphakathi yomsungulo, kanti amaminerali alula okungukuthi i-gangue ayacindezelwa ngaphandle.

Umklamo we-chute yesipikili uqinisekisa ukuthi i-flow velocity kanye ne-particle settling rates zilinganisela ukuze kuphumelele kakhulu ukubuyisa. Imifudlana yemikhiqizo eminingi ingaqoqwa ezindaweni ezahlukene eduze nesipikili, okuvumela ukuhlukaniswa okuthuthukisiwe kanye nokuthuthukiswa kwezinga.
